Yash Gourav Kar

Software engineer

with a track record of building end-to-end applications using React and TypeScript.

Having worked professionally since 2023 in a number of US startups (all in their 0–1 phase) made me take Founding Engineer responsibilities in a short span of time.

I'm currently learning building real time collaborative software with Replicache while using LLMs to elevate product experiences.
